[0030] The detection component is arranged above the pipeline body 3 and is used to perform a pressure test on the pipeline body 3.

[0031] Depend on Figure 1 、 Figure 3 and Figure 4 It can be seen that the guide wheel 8 is made of rubber material.

[0032] The adjustment assembly includes a positioning plate 9, a cylinder 10 and a cylinder shaft 11.
